网络请求框架----AsyncHttpClient的get,post和图片上传服务器

async-http-client库是一个基于回调函数的Http异步通信客户端Android组件，是在Apache的HttpClient库的基础上开发构建而成的。

Eclipse使用：导入android-async-http-1.4.4.jar包http://download.csdn.net/detail/dickyqie/9662215

AndroidStudio: gradle中引入compile'com.loopj.android:android-async-http:1.4.8'

 

功能特色

• 利用版4.3.6上游HttpClient代替Android提供defaulthttpclient
• 兼容AndroidAPI 23高
• 做异步HTTP请求处理的响应匿名回调
• HTTP请求发生UI线程之外
• 请求使用线程池限制并发资源使用情况
• get /后参数生成器（ RequestParams ）
• 多文件上传没有额外的第三方库
• JSON上传流没有额外的图书馆
• 处理循环和相对重定向
• 小的开销给你的应用程序只90kb一切
• 自动智能请求重试次数质量不一的移动连接优化
• 自动gzip响应解码速度超快的请求支持
• 二进制协议通信binaryhttpresponsehandler
• 内置的响应分析JSON与jsonhttpresponsehandler
• 节能反应直接进入文件fileasynchttpresponsehandler
• 大的持久性Cookie，保存cookie到你的应用程序的SharedPreferences
• 杰克逊JSON集成，gson或其他JSON序列化库（德）basejsonhttpresponsehandler
• 与SAX解析器支持saxasynchttpresponsehandler
• 语言和内容编码的支持，不仅仅是UTF-8

  效果图：

  

  案例如下：

public class MainActivity extends Activity implements OnClickListener {

	public static AsyncHttpClient mHttpc = new AsyncHttpClient();

	private TextView mTextView;
	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_asynchttpclict);
		initView();
	}

	private void initView() {
		findViewById(R.id.btn1).setOnClickListener(this);
		findViewById(R.id.btn2).setOnClickListener(this);
		findViewById(R.id.btn3).setOnClickListener(this);
		findViewById(R.id.btn4).setOnClickListener(this);
		mTextView=(TextView) findViewById(R.id.Text);
	}

	@Override
	public void onClick(View v) {
		switch (v.getId()) {
		case R.id.btn1:
			showHttpGet1();
			break;
		case R.id.btn2:
			showHttpGet2("https://www.baidu.com");
			break;
		case R.id.btn3:
			showHttpGet3();
			break;
		case R.id.btn4:
			showHttpPost();
			break;
		case R.id.btn5:
			
		case R.id.btn6:
			
		default:
			break;
		}

	}

	private void showHttpGet1() {

			}
